Background The purpose of this study was to evaluate the content and quality of YouTube videos on the topic of adult orthodontics. Methods Four Turkish keywords were searched on YouTube: ``orthodontic treatment in older ages'' (ileri yaslarda ortodonti tedavisi); ``orthodontic treatment in adults'' (yetiskinlerde ortodonti tedavisi); ``braces treatment in older ages'' (ileri yaslarda video information and quality index dis teli tedavisi); and ``braces treatment in adults'' (yetiskinlerde dis teli tedavisi). A total of 184 videos, ranked according to their relevance, were examined; out of these, 52 videos on the topic of adult orthodontics were included in the study. The information content score (with a scoring system consisting of 6 questions), reliability score, (VIQI), interaction index, and viewing rate of the videos were evaluated. The Mann-Whitney U test, Student's t test, and Spearman correlation coefficients were used for statistical analysis. Results Explanations provided on all videos included in the study were given by orthodontists, to inform patients. The average content score of the videos was 2.55 ± 0.99 out of 6, and the reliability score was 3.07 ± 0.92 out of 5. The VIQI score was found to be 16.05 ± 2.76 out of 20. A total of 34 (65%) of the videos were scored as as having poor content, and 18 (35%) had rich content. Rich-content videos were observed to be significantly longer (P Conclusions Although the information provided by YouTube videos about adult orthodontics was only moderately sufficient, this study found that YouTube is a reliable source of information.

Introduction As a result of the rapid spread of the disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the World Health Organization (WHO) declared a global pandemic on March 11, 2020. Governments around the world adopted various measures to stop or slow the spread of coronavirus disease 2019 (COVID-19). One widely used measure was “lockdown”; workers who could work from home were instructed to do so, and nonessential businesses – including dental clinics -- were closed for weeks or months. The purpose of this investigation was to document the incidence of fixed orthodontic appliance failures and the periodontal health status of patients undergoing fixed orthodontic treatment during and after the lockdown period. Methods The sample comprised 350 orthodontic patients (mean age 16.85 ± 2.59 years; 249 female, 101 male) who underwent orthodontic and periodontal examinations in Adıyaman, Turkey after a mean lockdown period of 103.7 ± 21.3 days. Frequencies of orthodontic bracket, elastic ligature, molar band, and miniscrew failures and of oral ulcers were recorded and periodontal parameters were assessed. The effects of sex, age, and the bracket systems used in the patients on the frequencies of these failures were analyzed. Results It was revealed that 15.42% (n=54) of all patients had at least one bracket bonding failure and 8.16% (n=4) of the patients with miniscrew implantation had at least one miniscrew failure. The incidence of bracket bonding failure was significantly higher in men than in women. No significant relationship was found between periodontal parameters and bracket bonding failure. Plaque and gingival scores were higher than those reported for a similar population before a lockdown. Conclusions The results indicated that orthodontic appliances may have higher frequencies of failure during a lockdown when compared with normal times and lockdown periods may worsen the periodontal health status of the patients.

BACKGROUND: Coronavirus disease (COVID-19) has led to unprecedented challenges in the arts, sports, education, finance, and healthcare. The aim of this study was to compare demographic characteristics of new-patient visits for orthodontic treatment in the pandemic year (2020) versus previous years. METHODS: The retrospective study included patients who sought care at a tertiary orthodontic referral center between January 1, 2016 and December 31, 2020. Clinical and demographic characteristics, including age, age group (child, young adult, adult), gender, and numbers of monthly and annual new-patient visits were compared between the pre-pandemic (2017-2020) and post-pandemic (2020) periods. The daily average numbers of appointments were compared for 2019 versus 2020. RESULTS: The average number of monthly new-patient visits was 240.69 ± 81.48 in the pre-pandemic period, as opposed to 113.75 ± 88.89 in the year 2020 (P < 0.001). The average number of monthly new-patient visits decreased by 48.3% in 2020 compared to 2019, while the average number of daily new-patient visits in 2020 decreased significantly in all months (P < 0.05), except for January (P = 0.613) compared to the monthly numbers from the previous year. No significant difference was found between the pre-pandemic period and 2020 with regard to gender (P = 0.410). In all years, the numbers of new-patient visits were higher for women, compared with men, and for children, compared with adults. CONCLUSIONS: The results indicated a sharp decrease in the number of new-patient visits for orthodontic treatment in the pandemic year (2020) compared to previous years.

The appropriate treatment of pediatric mandibular condyle fractures is subject to much debate and concern among surgeons, with improper treatment potentially resulting in a number of adverse outcomes. Such outcomes include the disruption of mandible growth, decreased posterior facial height, facial asymmetry, and temporomandibular joint ankylosis. Several surgical and nonsurgical approaches to these fractures have been described in the literature; however, each one carries its own risk of various complications. In this study, the authors illustrate a new atraumatic approach for mild to moderately displaced subcondylar fractures, with least possible complications and unexpected outcomes. In this study, 6 patients (2 female and 4 male) with unilateral medially displaced condylar base and neck fractures, angulated between 30 and 45 degrees, were treated using a novel intraoral approach. The follow-up period varied from 12 to 18 months. All patients achieved normal occlusion and had painless functioning of the temporomandibular joint with proper mouth opening (>35 mm) without any recurrence at long term follow up. This minimally invasive approach could eliminate the possibility of major complications and be considered a safe and feasible surgical technique for certain cases of pediatric mandibular condyle fracture.

Coeliac disease (CD) is a common disorder that usually originates from calcium malabsorption. Thus, it is accepted that patients with CD have lo- wer bone mineral density than that of healthy individuals. The aim of this study was to assess condylar height, width, area, and perimeter on digital panoramic radiographs in patients with CD.Panoramic radiographs obtained from 44 patients with CD were age- and sex-matched with 44 Class 1 (ANB: 2 ± 2°) patients, and out- comes were analysed. Radiographs were digitised using Image J software, and condylar height, width, area, and perimeter were compared.Condylar area (3.66 ± 1.02 cm2), perimeter (9.29 ± 1.38 cm), and height (2.69 ± 0.46 cm) values were significantly higher (p0.05) in the control group than those in the patient group (area: 2.52 ± 0.63 cm2, perimeter: 8.47 ± 1.42 cm, height: 2.51 ± 0.37 cm), whereas width (coeliac: 2.83 ± 0.63 cm, control: 3.00 ± 0.59 cm) did not differ between the groups (p0.05).These outcomes may be due to the low bone density of patients with CD. A controlled trial conducted using a larger sample is needed to support and extend these data.
